about this Topic

Minerals are a valuable natural resource. Those found in coastal environments include sand and gravel, while minerals such as phosphorites, iron-manganese crusts, and sulfides are found in deeper waters. CMG research aims to understand their distribution and the processes that control the composition, origin, and availability of such minerals.

Bulletin 2209-H: Stratiform Barite Deposits in the Roberts Mountains Allochthon, Nevada: A Review of Potential Analogs in Modern Sea-Floor Environment
Description: The United States is a net importer of barite, a critical mineral for the oil and gas industry; more than 80 percent of current domestic consumption of barite is imported from China. Nearly all of the domestic production of barite comes from stratiform deposits in Nevada. The "modern analogs" approach adopted in this review can contribute to improving deposit models and the long-term resource picture in the United States.

Open-File Report 2006-1036: Quantitative X-ray Diffraction Mineralogy of Los Angeles Basin Core Samples
Description: This report contains X-ray diffraction (XRD) analysis of mineralogy for 81 sediment samples from cores taken from three drill holes in the Los Angeles Basin in 2000-2001. We analyzed 26 samples from Pier F core, 29 from Pier C core, and 26 from the Webster core. These three sites provide an offshore-onshore record across the Southern California coastal zone. This report is designed to be a data repository; these data will be used in further studies, including geochemical modeling as part of the CABRILLO project. Summary tables quantify the major mineral groups, whereas detailed mineralogy is presented in three appendices. The rationale, methodology, and techniques are described in the following paper.

Research Project
Hydrates From Ice (HyFI)
Description: The HyFI facility is designed for making physical property measurements on a variety of hydrates. The term "Hydrates From Ice" refers to one formation technique in which hydrate is formed by slowly warming granular ice in a pressurized atmosphere of the hydrate former (methane, for instance). This methodology was developed at the USGS, in the Menlo Park laboratory lead by Dr. Stephen Kirby and Laura Stern.

Research Project
Marine Aggregate Resources and Processes
Description: The Marine Aggregates (Sand and Gravel Assessment) Project has developed and is implementing a scientifically rigorous series of regional studies mapping the seafloor sedimentary character and assessing marine sand and gravel resources around the United States. Results of the regional assessments will ultimately comprise a national assessment of marine sand and gravel. This study is responding to increasing demand for web-accessible GIS-type data and interpreted geologic map information on the sedimentary character of the seafloor and aggregate resources suitable for beach nourishment and coastal restoration, as well as seafloor sediment texture information for benthic habitat mapping and sediment transport studies.

The Escanaba Trough of Gorda Ridge: A Laboratory for Mineral-forming Processes - USGS Fact Sheet
Description: The Gorda Ridge is a unique geological system in the Exclusive Economic Zone of the United States. This tectonically and volcanically active plate boundary has an unusual morphology for spreading centers in the Pacific Ocean: a deep, wide axial valley flanked by high ridges. Because of its location near the continental margin, part of the axial valley known as the Escanaba Trough is covered by sediment. The Escanaba Trough provides opportunities for scientists to learn details about tectonics, volcanism, mineral formation, and biological activity that are not normally observed at mid-ocean ridges. It is a geological laboratory of grand proportions.

Evolution and History of Incised Valleys: The Mobile Bay Model - USGS Fact Sheet
Description: Incised valleys along the Gulf coast commonly result from rivers eroding rapidly in response to a fall in sea level. As sea level rises, sediments fill incised valleys and form nearshore elongated sandbodies such as barrier islands. These sandbodies can be potential sites for hard-mineral accumulations and are modern analogues to buried sands in the ancient rock record with high potential of being oil and gas reservoirs. Processes that formed residual sediment accumulations may also help to predict the outcome of man's erosion mitigation and wetland nourishment efforts. Today, the geologic imprint of incised valleys across the continental shelf provides evidence of sea-level change over the past 18,000 years.

Lake Baikal - A Touchstone for Global Change and Rift Studies - USGS Fact Sheet
Description: The Lake Baikal rift system is a modern analogue for formation of ancient Atlantic-type continental margins. It tells us the first chapter in the story of how continents separate and ultimately develop into ocean basins like the Atlantic Ocean.

An Overview of Coastal Land Loss: With Emphasis on the Southeastern United States
Description: In states bordering the Gulf of Mexico and the Atlantic Ocean, vast areas of coastal land have been destroyed since the mid 1800s as a result of natural processes and human activities. The physical factors that have the greatest influence on coastal land loss are reductions in sediment supply, relative sea level rise, and frequent storms, whereas the most important human activities are sediment excavation, river modification, and coastal construction. As a result of these agents and activities, coastal land loss is manifested most commonly as beach/bluff erosion and coastal submergence.

Data Set
U.S. Geological Survey Open-File Report 03-001, Title Page
Description: This report contains surficial sediment data from previously unpublished data sources or from gray literature. These data have been compiled as part of the National Benthic Habitats and Marine Aggregate Resources and Processes Projects to update the existent maps on surficial sediment distribution available for the Gulf of Maine region. Sediment data in this report are GIS ready and are broken into data layers by their original source project. The data layers are provided as single-point vector datasets with sample identifiers, navigation, textural attribute information, and FGDC compliant metadata.
